Caterpillars are still eating my broccoli.
I've just picked a few off and thrown them a long way away.

This bit puzzles me, why on earth didn't you kill them?
The chances are that they would be back on your broccoli
before you turned round!

I can't justify not killing them!
Sometimes one just acts in a particular manner without knowing why.
Then an attempt to answer a question like yours can result in post-hoc
rationalisation.
And ... in asking "Why?" you might be seeking an answer in terms of
causation; or an answer in terms of teleology.
Though ... you may in fact be saying, "Idiot!"
